Questions: Groupthink and Consensus-Seeking in Decisions

Question 1

A team of highly experienced, intelligent engineers is cohesive and works well together. Their respected leader expresses a strong preference early in the meeting. Under deadline pressure, the team approves a design despite one member's serious safety reservations, which she keeps to herself. What is the most likely explanation for the flawed outcome?

• A. The engineers lacked sufficient technical expertise to evaluate the design correctly
• B. The dissenting member was wrong, and the team correctly outweighed her individual concern
• C. Groupthink: structural conditions — directive leadership, cohesion, and pressure — led the member to self-censor to maintain group harmony rather than voice a legitimate concern
• D. Group polarization pushed the team toward the leader's preferred extreme position

Answer: (C)

This scenario contains all the classic groupthink antecedents: a directive leader who signals their preferred outcome early, high cohesion, and deadline pressure creating a sense that alternatives are costly. The result — self-censorship of a legitimate concern — is the symptom Janis called 'self-censorship.' Option A is the most tempting distractor: it assumes the problem is incompetence, when Janis's central finding was that groupthink occurs *especially* in smart, expert groups. Option D is related but distinct: group polarization describes the drift toward extremes in discussion, not the suppression of dissenting information.

Question 2

Which intervention most directly counteracts the role of directive leadership as a groupthink antecedent?

• A. Reducing the group's size to make communication easier
• B. Having the leader share their preferred outcome only after all members have deliberated freely
• C. Assigning a devil's advocate role to the most senior member
• D. Holding a vote by secret ballot at the end of deliberations

Answer: (B)

When a leader states their preference early, it creates a powerful anchor: members face social pressure to align with the leader, and dissent becomes an implicit act of disloyalty. Delaying the leader's disclosure removes this anchoring effect and allows genuine deliberation before the social pressure of conforming to authority kicks in. Option C (devil's advocate) addresses the absence of structured dissent, which is a different antecedent — lack of procedural norms. Option D helps with social conformity pressure but does not address the leader's early signaling problem specifically.

Question 3

Groupthink is more likely to occur in groups composed of intelligent, expert members than in groups of ordinary people, because experts have stronger in-group loyalty.

• T. True
• F. False

Answer: False

Janis's central finding was precisely the opposite: his case studies — the Kennedy cabinet, NASA engineers — involved highly intelligent, expert groups. Expertise provides no immunity to groupthink because the phenomenon operates through structural and situational conditions (cohesion, insulation, directive leadership, pressure), not through individual cognitive capacity. The mechanism is social-motivational, not intellectual: the desire to maintain group harmony and approval becomes stronger than epistemic motivation, regardless of how smart the members are. High expertise may even worsen groupthink by strengthening in-group identity and confidence.

Question 4

High group cohesion is a necessary but not sufficient condition for groupthink — many cohesive groups make excellent decisions.

• T. True
• F. False

Answer: True

Janis was explicit about this: cohesion alone does not produce groupthink, and reducing cohesion is not the right intervention (it would impair many positive group functions). Cohesion becomes dangerous when combined with specific additional conditions: insulation from outside viewpoints, a directive leader who signals a preferred outcome, high-stress conditions with a perceived absence of alternatives, and weak procedural norms for structured deliberation. The right response to groupthink risk is not to make groups less cohesive but to build procedural safeguards that protect critical evaluation.

Question 5

Why is assigning a formal devil's advocate role more effective at preventing groupthink than simply encouraging all members to speak up freely?

Model answer: When members are merely encouraged to voice dissent, raising objections still feels like a personal act — one that risks social disapproval, challenges the leader, or threatens group harmony. The social pressure against dissent remains. A formally assigned devil's advocate role changes the social meaning of criticism: it becomes a structural feature of the process, not a personal choice. The member is not expressing doubt; they are performing an assigned function the group has sanctioned. This decouples the act of voicing criticism from its social costs, allowing legitimate concerns to surface without triggering the social dynamics that make self-censorship attractive.

The distinction is between changing the incentives for individuals (encouragement) versus changing the social structure of the decision process (role assignment). Groupthink is a structural problem — it arises from how the group is organized. Structural solutions (devil's advocate, second-chance meetings, subgroup deliberation) address the root cause more reliably than appeals to individual courage.
